The aim of this series is to provide a scholarly forum for current theoretical and empirical issues in cognitive and perceptual development. Contemporary explanations build on the combined influences of biological, cultural, contextual and ecological factors in well-defined research domains. In the field of cognitive development, cultural and situational factors are widely recognised as influencing the emergence and forms of reasoning in children. In perceptual development, the field has moved beyond the opposition of 'innate' and 'acquired' to suggest a continuous role for perception in the acquisition of knowledge. These approaches and issues will all be reflected in the series.
